<span><u><em>Answer:</em></u>
non-renewable energy resources are the ones that can be used up
<u><em>Explanation:</em></u>
<u>Energy resources can be classified into two categories:</u>
<u>1- non renewable resources:</u> these are the energy resources that cannot renew themselves. They are the resources that are formed from sources that can be consumed and run out. All fossil fuels are considered non renewable resources

Examples of renewable resources: solar energy, wind energy,.....
Based on the above, the energy resource that can be used up is the non renewable energy resource.

Assuming the planet can be treated as a solid sphere,
(9.74 x 10^37 kg-m²) = (2/5)(5.98 x 10^24 kg)R²
R = 6.38 x 10^6 m
Answer:
T= 4.24sec
Explanation:
We are going to use the formula below to calculate.
Where T is period
L is length of rod
g is acceleration due to gravity = 
From the problem, the rod is pivoted at 1/4L which means that three quarter of the rod was used for the oscillation. lets call this 
= 4.4625m
thus 
T= 4.24sec
